EEPROM Control (42h)

State machine commands for loading EEPROM data after reset. (see extended EPROM configuration)

HALT

Writing a 1 to this bit stops the reading of EEPROM data.

SKIP

Writing a 1 to this bit forces the next EEPROM read cycle to occur at the address held in the

Configuration Control (n) register, where "n" is the value held in the Configuration Index Regis-

ter (43h)

JUMP

Writing a 1 to this bit forces the next EEPROM access to occur at the address held in registers

40h and 40h.

Configuration Index Register (43h)

This contains the DIP switch status at reset. (see extended EPROM configuration) The value of this register selects

the appropriate Configuration register when the SKIP command is executed.

Reserved Registers (44h - FEh)

These registers are reserved and return a value of 00h when read.

Station Address Register (FFh)

CS7666 station address, 7 MSBs (the LSB of the complete 8-bit station address is determined by the LSB which

acts as a read/write direction bit).
